In Greek mythology, the titan Prometheus stole fire and gave it to humans, creating civilization. As punishment, Zeus bound him to a rock and each day sent an eagle to eat his liver, the organ where the Greeks thought human emotions resided. The moral of the story is knowledge brings eternal emotional torment. In the Garden of Eden, the serpent tempts Eve and Adam to eat forbidden fruit from the Tree of Knowledge. God punishes them by banishing them. The moral of the story is knowledge destroys innocence and produces suffering.
